ENERGY STAR homes must meet certain guidelines established by the Environmental Protection Agency. There are six required areas:
4. Efficient Heating and Cooling
Equipment
In addition to using less energy to operate, energy-efficient
heating and cooling systems can be quieter, reduce indoor humidity, and
improve the overall comfort of the home. When properly installed into a
tightly sealed home, this equipment won't have to work so hard to heat and
cool the home.
3. Tight Construction and Ducts
Sealing holes and cracks in the home's "envelope" and in
heating and cooling duct systems helps reduce drafts, moisture, dust,
pollen, and noise. A tightly sealed home improves comfort and indoor air
quality while reducing utility and maintenance.
2. High-Performance Windows
Energy-efficient windows employ advanced technologies, such
as protective coatings and improved frames, to help keep heat in during the
winter and out during the summer. These windows also block damaging
ultraviolet sunlight that can discolor carpets and furnishings.
1. Effective Insulation
Properly installed and inspected insulation in floors, walls,
and attics ensure even temperatures throughout the house, reduced energy
use, and increased comfort.
5. Efficient Products
ENERGY STAR qualified homes may also be equipped with ENERGY
STAR qualified products— lighting fixtures, compact fluorescent bulbs,
ventilation fans, and appliances, such as refrigerators, dishwashers, and
washing machines.
6. Third-Party Verification
With the help of independent Home Energy Raters, ENERGY STAR
builder partners choose the most appropriate energy-saving features for
their homes. Additionally, raters conduct onsite testing and inspections to
verify the energy efficiency measures, as well as insulation, air tightness,
and duct sealing details.
